Omni achieved an overall score of 817, compared with the average 791 score for the upscale segment, the company said in a news release. The study is based on responses from over 53,000 guests who stayed in a hotel from May 2009 through June 2010.

“Our brand culture is relentlessly focused on delivering exceptional service to our guests,” Omni President Mike Deitemeyer said in the release. “This ranking is a testament to our outstanding associates and unique luxury properties, which incorporate the authentic local flavor of a destination, creating a truly memorable experience for both business and leisure travelers.”

J.D. Power’s upscale category also includes hotel chains like Doubletree, Embassy Suites, Hilton, Hotel Indigo, Marriott, Renaissance and Sheraton. Marriott also is a contender to run the convention center hotel.
